GRAIN- METER.

SPECIFICATION forming part of Letters Patent No. 283,351, dated August 14, 1883.

Application filed May 19, 1883. (K model.)

1'0 all whom it may concern.-

Be it known that LGEORGE B. LYNCH, a citizen of the United States, residing at Dar- 'lington, in the county of Montgomery and State of Indiana, have invented certain new and useful Improvements in Grain-l\Ieasures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. I

Figure 1 of the drawings is arepresentation of a front view of this invention. Fig. 2 is a vertical section thereof.

This invention has relation to the buckets or boxes of grain-meters, being an improvement on the devices described in Letters Patent No. 270,821, granted to Geo. B. Lynch and Thos. J. Griffith January 16, 1883.

The invention consists in the construction and novel arrangement of the pivoted slats forming the bottoms of the buckets, their arms, the connecting-rods, and the cam devices designed to effect the Opening and closing of the bottoms automatically as the buckets fall and rise, respectively, in their chambers, all as hereinafter set forth.

In the accompanying drawings, the'letter A designates the incasement 0r frame-box of the meter, having the hopper B. It is divided into chambers or ways, in which are arranged the suspended buckets O and D. E E represent the pivoted slats forming the bottoms of these buckets. The slats are pivoted to the bucket -walls by end pivots, a, and are provided with crank-arms F, which are pivoted to horizontal connecting-bars G. The slats of each bucket are in this manner connected,

so that they willmove simultaneously. The

lever arms or cranks F are exterior to the bucket-walls, as shown in the drawings. The bottom of each bucket is provided with a rollerstud, b, which engages a vertical guideway or cam-slot, H, so that the buckets are kept true as they rise and fall, moving in straight vertical lines. The connecting bar G of each bucket is provided with a roller-stud, c, which engages a cam slot or guide, K, having a lateral oblique bend or curve at d. Above and below this curve or bend the guide is vertical. As the bucket on one side, being filled, descends, the connection G, operated by the cam slot or guide, causes the upper ends of the crank-arms F to move laterally, throwing the slats into oblique or open position. At the same time the bucket on the other side, being empty, rises, and its cam slot or guide open ates the arms thereof automatically through the connection-rod to close the slats together, so that the bucket will be ready to receive its load. The slats are formed with beveled or rabbeted edges, as indicated at (2, so that they will close together squarely and form a level bottom. 7

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

I11 agrain-meter, the rising and falling buckets having pivoted slats forming the bottoms thereof, crank-arms rigidly connected to said slats and pivoted to connection-bars, and cam slots or guides adapted to engagethe connection-bars and open or close the slats automatically as the buckets descend or rise, substantially as specifieds In testimony whereof I affix my signature in presence of two witnesses.

GEORGE B. LYNCH.
